Abstract

The Object Constraint Language (or variations of it) is increasingly being used as a text based navigation or expression language over Object-based modelling languages other than the original target of UML. The recent increase of Domain Specific Languages has in particular contributed to this process. As a consequence, it is useful to investigate the lengths to which an OCL like expression language can be made independent of the specifics of the underlying modelling language, concepts and implementation. This paper looks at the issue from the perspective of detaching the OCL specification from the standard library of types that is currently built into its definition.
